Honestly, I have no idea what is going on in sqr. Andy Wolff has created an incredibly erratic and confused shmup which is simple yet quite beautiful looking.

Made completely out of squares, your ship will automatically fire randomly around the screen at the incoming enemies. Hold Z and a concentrated laser will plow through the small blue square following your ship, destroying anyone in that direction. A huge explosion can also be charging using X. (Note that pressing R will restart the game after death)

Part of its charm is the way in which the enemies appear to approach in such an indecisive manner, yet now and again they'll form pathways for your ship to drive through, then suddenly turn nasty and surround your ship. It's a bit like watching one of those simple artificial life simulators.
